This broad category of elements will all tend to lose electrons when they become charged.
What are metals?
100
This guy stated his theory explaining how atoms combined in certain ratios but incorrectly deduced that atoms were indestructible.
Who is John Dalton?
100
The type of bond associated with a transfer of an electron from a metal to a nonmetal.
What is an ionic bond?
100
All other elements are jealous and envious of the configurations that these elements have.
What are noble gases?
200
A phase change, such as melting or freezing is always this type of change in matter.
What is physical change?
200
Nonmetals will gain electrons to complete their energy level in attempt to achieve this.
What is an octet/noble gas configuration?
200
Showed us that atoms are mostly just empty space with a dense region of positive charge called a nucleus.
Who is Ernest Rutherford?
200
Magnetic-like interactions between these types of molecules, resulting from moderate electronegativity differences and an unequal sharing of electrons.
What are polar covalent compounds?
200
These wannabe's sometimes act like metals. Other times, not so much.
What are metalloids?
300
A change in energy (heat absorbed or released) usually accompanies this type of change in matter?
What is chemical change?
300
These are the only electrons that can be gained or lost from an atom.
What are valence electrons?
300
Correctly explained the emission spectra of simple atoms by showing how electrons can transition between excited and ground states by absorbing and emitting energy in the form of light.
Who is Neils Bohr?
300
These bonds between nonmetals with small differences in electronegativities result in an equal distribution of electrons.
What is a nonpolar covalent bond?
300
How many of these elements does it take to screw in a light bulb? It doesn't matter because they couldn't be used to turn it on anyway.
What are nonmetals?
400
This is a physical change of state characterized by a liquid sample turning into a gas without actually boiling.
What is evaporation?
400
Atoms within this group do not typically form ionic compounds because it's very hard for them to gain or lose that many electrons.
What is Group 4A?
400
Discovered the first subatomic particles, corpuscles, that later became known as electrons.
Who is JJ Thomson?
400
This is the charge carried by an ionic compound composed of cations and anions.
What is neutral/zero?
400
These elements can have multiple pseudo-stable configurations and therefore it is more difficult to know their charge.
What are transition metals?
500
A physical change of matter characterized by placing a solid substance in water and having it 'disappear'.
What is dissolving?
500
Cations and anions combine in specific ratios to form ionic compounds with this charge.
What is zero (or neutral)?
500
This oddball defined the order in which electrons entered energy levels, with the lowest energy levels being filled up first.
Who is Aufbau?
500
Not shockingly, this category of elements form covalent molecules when combining with each other.
What are nonmetals?
500
Not quite noble and very reactive, this group of elements are often used as disinfectants and antibacterial agents.
